Embodiment
Below in conjunction with embodiment, the utility model is described further, better to understand technical solutions of the utility model.
Embodiment 1: the flow control of a kind of gas recovery system for oil vacuum and gas-liquid ratio adjusting valve, see Fig. 1, Fig. 2 and Fig. 3, comprise valve chest 1, be set with the barrel 6 of isolation oil circuit and gas circuit at valve chest front end inner chamber, being leading portion gas circuit B inside described barrel 6, is leading portion oil circuit A outside barrel, be provided with inside barrel for the spool 9 closed and open leading portion gas circuit path and the driven magnet 7 be connected as a single entity with spool 9, described spool 9 end is provided with tapered end 10.Leading portion oil circuit A outside barrel is provided with the active magnet 8 being driven movement by oil stream, active magnet 8 one end is provided with elastic component 11, and the present embodiment Elastic part is spring.When nozzle refuels, oil stream in oil circuit path A drives initiatively magnet 8 to move towards oily flow path direction, driven magnet 7 moves with active magnet under the driving of attraction force, and then band mantle core moves with oily flow path direction, because oily flow path direction is contrary with airflow direction, open gas circuit passage opening after cone core moves, realize petroleum vapor recovery.Otherwise when the oil stream in oil circuit path A reduces, initiatively magnet 8 orders about reply initial position by elastic component, drive driven magnet to move along airflow direction, order about cone core and close gas circuit passage opening.The oil stream flow velocity that refuels is different, the amount of deformation of elastic component is different, and then cause the amount of movement of initiatively magnet different, initiatively the amount of movement of magnet determines the matching gap between cone core and gas circuit passage opening, namely the size of air flow rate is directly proportional to gap length, and the air flow rate therefore achieving petroleum vapor recovery is in direct ratio with oiling oil mass.
Back segment gas circuit B and back segment oil circuit A is provided with in described valve chest rear end, described back segment gas circuit communicates with leading portion gas circuit, described back segment oil circuit communicates with leading portion oil circuit, the open and close controlling part of described back segment gas circuit is: in valve chest 1 rear end, inwall is provided with elastic diaphragm 3, described diaphragm 3 lower end is connected with spring 4, spring 4 the other end is connected to and is positioned on the valve wall of spring bottom, described back segment gas circuit comprises passage one B-1 of the vertical connection leading portion gas circuit arranged, passage two B-2 be arranged side by side with passage one, passage three B-3 of the cross setting communicated with passage two, described passage three exports with gas circuit and is connected, described leading portion gas circuit is communicated with liquid passage inlet, in passage two upper end and diaphragm corresponding position, a raised seals face 5 is set, vent is left in raised seals face 5, namely matching gap between diaphragm and raised seals face forms the opening and closing passage of back segment gas circuit, the viewing window 14 for observing diaphragm position is provided with in valve chest rear end, and the air hole 15 to communicate with valve chest inner chamber, and by-pass hole 12 is provided with on passage two.Be specially: diaphragm moves down, when fitting with raised seals face, passage two is obstructed with passage one, back segment gas circuit is closed, and only enters a small amount of air-flow from by-pass hole, and gas liquid ratio reduces, can be adjusted between 0.1-1.0, for vehicle-mounted oil filling petroleum vapor recovery (ORVR) system, diaphragm moves, passage one air-flow can along vent inlet passage two, back segment gas circuit is opened, gas liquid ratio increases, and can be adjusted between 1.0-1.2, for gas station's secondary oil gas reclaiming system.In order to better regulate back segment gas channels, regulate gas liquid ratio more accurately, the valve chest corresponding with passage two is provided with the adjusting screw 13 that can regulate passage two cross section.Adjusting screw 13 extend on passage two, stretches into degree, i.e. adjustable passage two channel sized by adjustment adjusting screw 13, and then adjustment air flow rate.
The present embodiment, on the basis of gas-liquid ratio adjusting valve, has directly been set up the vacuum conditions part of one, has been regulated, achieve the gas liquid ratio of relative broad range by vacuum aided.The present embodiment valve body is possessing on vacuum Flow-rate adjustment and the multi-functional basis of gas-liquid proportion adjustment, valve body structure is simplified more, miniaturization.Eliminate attachment portion, save cost of production, simplify installation procedure, nozzle refuel time, use, more convenient to operate, reduce rate of fault.
The present embodiment working procedure is as follows:
1, the present embodiment gas recovery system for oil vacuum flow control and gas-liquid ratio adjusting valve, when using in gas station's secondary oil gas reclaiming system, nozzle front end is connected with oil tank of vehicle by leather cup, because fuel tank oil gas exists vapor tension, when nozzle refuels, vacuum pump running provides the vacuum of foundation to overcome spring force, spring is in extended configuration, diaphragm not with valve seal, diaphragm is full open position, back segment gas circuit B is in and opens channel status completely, and now petroleum vapor recovery reaches between gas liquid ratio 1.0-1.2.Meet the needs of gas station's secondary oil gas reclaiming system gas liquid ratio, namely put the gun refueling in process, under vacuum assist system effect, reach the requirement that gas liquid ratio is greater than 1.
2, when vehicle-mounted oil filling petroleum vapor recovery (ORVR) system uses, nozzle front end is connected with oil tank of vehicle by leather cup, the peculiar design of fuel tank, fuel tank oil gas can not spill into nozzle by reservoir port, when nozzle refuels, nozzle front end confined space is less, vacuum pump running easily sets up vacuum, vacuum can overcome spring force, spring is in complete compressive state, and diaphragm and valve body are fitted, sealed, and diaphragm is in closes shape body completely, gas circuit is only by the by-pass hole return-air on passage two, and this formula gas liquid ratio that petroleum vapor recovery reaches is between 0.1-1; The needs of vehicle-mounted oil filling petroleum vapor recovery (ORVR) system gas liquor ratio can be met, namely put the gun refueling in process, under vacuum assist system effect, reach the requirement of gas liquid ratio <1.
